IMPROVEMENT IN MACHINES FOR PERFORATING PAPER.

Specification forming part of Letters Patent No. 196,395, dated October 23, 1877; application led August 14, 1877.

in the accompanying drawings, of which- Figure l is a side elevation, Fig. 2 an end view, and Fig. 3 a longitudinal section, of it.

Fig. 4 is a top view'of the foraminous patternplate and its carrying-frame. Fig. 5 is a longitudinal section of such plate and frame, and its backing-plate and pins.

In such drawings, AA denote parallel ways or rails for supporting and guiding the backing-plate B and the pattern-plate C when connected. These rails are arranged within a press-frame, D, provided with a platen, E, and mechanism for moving it up and down, such mechanism, as shown, consisting of a connecting-rod, a., and a shaft, l), furnished with arms c d, all arranged as represented.

Thebacking-plate B has upon it, and connected to it bylocking-pins e e, the frameF, supporting the plate O, which is perforated with numerous small holes, arranged at equal distances apart, both lengthwise and widthwise of it. Up through these holes a series of headed and pointed pins, f j', are to be eX- tended, as shown, their heads resting upon the plate B, which is to keep the pins in place in the foraminous plate. By marking or placing upon the back of the foraminous plate any design, and -filling all or a sufficient number of the holes directly under the boundaries or lines of it with the pins, and securing them in place by the backing, connected by suitable fastenings to the pattern-plate, the press will be provided with means of puncturing a sheet of paper with holes for stenciling the design upon a wall or article.

In connection with the press, the foraminous plate and its backing, and series of pins, I make use of a device or mechanism for separating the perforated sheet from the pins. This is shown at G, and consistsof a rectangular frame, It, and a covering, t', thereto, of cloth, stretched across such frame fromside to side,

' and from end to end of it. The frame is to be laid upon that of the foraminousA plate and its pins, with the latter extending up through the cloth. The platen is to have holes or punctures in it, corresponding generally in number, positions, and size to those of the patternplate, in order that, while the platen is in'the act of being depressed upon the sheet to be punctured, the pins shall enter the platen.

Pendulous hooks or latches 7c 7c, as shown,

suspendedfrom the ends ofthe platen, are, during its descent, to catch upon studs Z l, projecting from the card-separator G, in order that while the platen is in the act of being' moved upward, such separator may be raised with it, and pull the card off the pins. The separator, on being withdrawn from the pins by the hand or hands of an attendant, will perform the office of separating the card from the said pins.

I claim as my invention as follows, viz:

l. The combination of the separator G withI the foraminous plate 'O,the series of pins f, and the backing-plate B, all being substantially as and for use as set forth.

2. The combination of the press, having perforations in its platen, as described, with the foraminous plate C, the series of pins j', the

' backing-plate B, and the separator G, all bemechanism, as shown, consisting of the pendulous hooks or latches 7c 7o and the studs l I,

applied to the platen and the separator, as set forth.
